What kind of batteries can I use on a PS1?

I want to make a super easy PSone portable. Practically, I just want to make my screenified PSone run off of batteries. Any suggestions?

I'm using some rechargeable AAs.

NiMh, 2650mAh Duracells, to be specific. Bought at Wally World for $15 for a pack of 8.

I also picked up some Digital brand rechargeables. They're also nickel-metal hydride, but have a capacity of 2500mAh.

I highly recommend you build it to run off of AA size batteries, since they are so common. You can get battery holders at Radio Shack that use regular 9v battery style connectors. (I was going to use catalog #<a href="http://www.radioshack.com/product/index ... 270-407</a>, but 2 AAs high is too thick for my design, so I'm going to stick together a #<a href="http://www.radioshack.com/product/index ... 270-391</a> and a couple #<a href="http://www.radioshack.com/product/index ... 0-401</a>s to create a custom sized battery pack, which can fit behind the screen or under the controller board. You'll see if I ever finish and upload the Sketchup model and images...)

Okay, I think I need some clarifying.

I don't want to mod the PSone in any way. I want to make an external battery pack. I want tips on how to make a battery pack.

That's even easier!

Get a project box and a battery holder, or glue a couple of their enclosed battery packs together, back to back. Then find a universal power supply adapter (Rat Shack used to call them "Adaptaplugs") and connect the battery pack to it. Use a multimeter to check for correct polarity before you plug it into the PSone! According to mine the tip (inside the plug, where the pin goes) is positive and the ring (the outside you can tough) is negative, but double-check it anyways. If you reverse the polarity you'll almost definitely mess the system up. Solder everything up and use electrical tape to insulate and secure the plug. Then it will work fine.

It sort of works like this, but you're not using an RC battery pack, and you probably don't want to sacrifice the wall adapter...

Oh yeah and make sure the voltage is correct! Too little and it won't work. Too much and it will fry.

heh, my old PS1p had exactly what bic was talking about, a detachable battery pack made from RadioShnot parts. But apparently my crappy porta-potty of a site site has gone down again. Just follow bic's directions and you should have it going in no time.
